Retrofit external coolant driven tools into internal through-coolant systems with industrial-grade Coolant Supply Systems for Driven Tools (Re-Cool coolant flush nut attachments). Designed to mount directly onto standard ER collet chuck outputs on live tooling units, this compact external-to-internal coolant ring system converts standard driven tools to internal coolant delivery in minutes. Featuring a flexible high-pressure metallic hose and a precision-sealed rotating collet nut, it supplies high-pressure coolant directly through the cutting tool center or around the tool shank, ensuring optimal chip evacuation, temperature control, and extended cutter life during intense milling and drilling operations.
